This topic describes how to stop and disable FirewallD on RHEL 7.Prerequisites
- You should have successfully installed RHEL 7 before this task.
If you have existing firewall rules on your host machines, you must disable the firewall in order to install Eucalyptus . You should re-enable it after installation.
Note
The firewall on a RHEL 7 system is enabled by default. Before you restart the CLC, you must disable the firewalld service on all host machines.
For more information, see FirewallD on RHEL 7 or FirewallD on CentOS .
To stop and disable FirewallD Check the status of the firewalld service:
systemctl status firewalld.service
The status displays as active (running) or inactive (dead) . If the firewall is active / running, enter this command to stop it:
systemctl stop firewalld.service
To completely disable the firewalld service, so it does not reload when you restart the host machine:
systemctl disable firewalld.service
Verify the status of the firewalld service:
systemctl status firewalld.service
The status should display as disabled and inactive (dead) .
firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
Active: inactive (dead)
Repeat these steps for all host machines. The firewalld service is stopped and disabled. You can now start the CLC and other host machines.
Postrequisites
- You should re-enable the firewall after installation is complete.
